1. 11.3 Using Data Displays Two types of data: Categorical- data that consists of names, labels, or other non- numerical values such as animals or colors Numerical- data that consists of numbers, such as weights of animals ES: Explicitly assess information and draw conclusions

2. Types of Data Displays and their benefits Line Graph- used to display numerical data over time Line Plot - used to show how often numerical data occurred Scatter Plot - Used to see trends in paired numerical data

3. Types of Data Displays and their benefits Stem and Leaf - organizes numerical data by its digits Box and whisker - organizes numerical data into four quarters and shows the distribution of the data

4. Types of Data Displays and their benefits Bar graph - Used to compare categorical data Circle graph - used to represent categorical data as part of a whole

5. Misleading Data Displays What makes these graphs misleading? How are they misleading? 1.) The broken vertical axis exaggerates the differences in the bar lengths 2.) The large increments on the vertical axis minimizes the change in the data 3.) The different bar widths suggest a comparison of area not lengths
